问题描述
我正在尝试使用ngModel来获取所有形式上的值，但是有些方法是我仅获取第一个文本框值.单击按钮后未获得添加的文本框值.
I am trying to fetch all the values which are in form using ngModel but some how I am getting only first text boxes values. Not getting textbox values added on click of button.
示例: stackblitz
html:
<form #profileSetUpForm="ngForm" (ngSubmit)="saveData(profileSetUpForm)" class="form ">
<div class="row m-0">
<div class="col-lg-12 col-md-12 col-sm-12 col-12 profile-input-label">
Tab Name
</div>
<div class="col-lg-4 col-md-12 col-sm-12 col-12 mt-top-5">
<input type="text" [(ngModel)]="tabName" name="configtabName" value={{tab}} placeholder="Tab Name" class="common-input form-control">

<div class="col-lg-4 col-md-12 col-sm-12 col-12 pr-0">
<div class="col-lg-12 col-md-12 col-sm-12 col-12 profile-input-label">

在addTile上单击时，将在新组件中添加以下html:
On click of addTile below html will be added which is in new component:

saveData(form : NgForm) {
this.postData = form.value;
// console.log('postdata:', this.postData);
let jsonData = this.postData;
console.log('jsonData', jsonData);
}
